Weekly Stat-Pac: Defense Week 12

on

As with the offensive side of the Stat-Pac, the defensive side now has all new graphs. We are still looking at the same data, but in a different set of relationships. We think the new look will make the data more interesting and meaningful for our readers. We are also repositioning the graphs to be first and then the bullet points explaining the details.

New Graph: Score Allowed by Quarter

Next ASU Opponent: Washington State

Here is a look at ASU’s next defensive opponent the Washington State Cougars comparing how the team has done so far this year versus the results from all of 2013.

Points allowed per game……2014—38.0…….…..2013—32.5
Yards allowed per game.……2014—454…………2013—-458
Turnovers per game…….……2014—-0.7…………2013—-2.3
Giving up red zone TDs……..2014—57%………..2013—-57%
3rd down conversion rate….2014—38%……….2013—-38%
Completions % allowed…….2014—65%………..2013—-63%
Havoc Rate………………………2014—17.9%……..2013–16.0%
Sacks per game………………..2014—-2.7…………2013—-2.5

The two big differences between this year’s defense compared to last year is that this year’s squad is giving up almost a touchdown more per game than in 2013 and getting far fewer turnovers. Most all the other defensive categories are pretty much the same for both years, except maybe an improved Havoc Rate so far this year.

Let us know what you think of our weekly Stat-Pac for the defenses in the conference, and also the Havoc Rate. Impacting the opponent’s offense and quarterback is a mainstay of a Todd Graham defense, and why we began tracking the Havoc Rate for ASU and the conference.

Gary graduated from ASU many years ago. After careers working in banking, finance and the financial administration of academic research funding, he is now interested in utilizing his passion for numbers towards two things he thoroughly loves; Arizona State University and college football. He is looking forward to finding the “stories” buried within the numbers on a football stat sheet. He has gone to ASU football games all the way back to the days of Frank Kush and the WAC. He has been married to an amazing ASU graduate for almost forty years, and they currently live in Ventura, CA. Although this may disqualify him from talking football, he and his wife enjoy the practice of yoga and dancing the Argentine Tango. Ole!
